ADOLPH MONSEN, OF CHICAGO, ILLINOIS, ASSIGNOR 0F ONE-HALF TO GEORGE C.REW, OF CHICAGO, ILLINOIS.

AUTOMOBILE TRACTION DEVICE.

Application filed January 2, 1913.

To all whom it may concern:

Be it known that I, ADoLrr-r MONSEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Automobile TractionDevices, of which the following is a specification. I

The principal object of my invention is to provide a new and improveddevice by which an automobile may be pulled out of a bad place in theroad by means of its own power.

Another object of my invention is to provide a winding drum on theautomobile which may be used in conjunction with a cable to pull theautomobile out of a place in which it may have become stuck.

These objects and various others will be made apparent in the followingspecification and claims, taken with the accompanying drawings, inwhich, for the purpose of illustration, I have shown onespecificembodiment of my invention.

Itwill be understood that the invention is defined in the appendedclaims. I

Referring to' the drawings,-Figure 1 is-a perspective view of anautomobileshowing my improvement applied thereto; Fig. 2 is a transversevertical section behind the gear casing of the automobile, lookingforward;

Fig. 3 is a fragmentary detail vertical section taken on the line 3 inFig. 4, lookmg in,

the direction of the arrow; Fig. 4 is a longitudinal vertical sectiontaken on the line 4 in Fig. 2, looking in the direction of the arrow.

As shown in the drawings, the automobile comprises the usuallongitudinal side frame member 15 for the chassis, the longitudinaldrive shaft 16 and the transmission gear casing 17.

18 is one gear wheel of the transmission system; more particularly, itis a gear wheel which is. utilized onlywhen the reverse gears are beingoperated. Adjacent to the gear wheel 18 is the casing 19, with theremovable cap 20, within which is a short longitudinal shaft 21 carryinga gear wheel 22 which engages the shaft 21 by means of a slot and keyconnection 47. Integral with the wheel 22 is a collar 23 with an annularslot engaged by a fork 24 that depends from the longitudinal slidingshaft 25. This shaft' 25 has its bearings at 28 and 29 in the walls ofthe casing 19. On its upper side it car- Specification of LettersPatent.

ries two shallow notches '26 adapted to be alternatively engaged by thelocking dog 27. WlllCh is pressed down by a spring within the housing27. The rear end of the rod 25 is pivoted at the lower end to the handlever 30, which has its fulcrum at 31 just below the walls of the casing32. At its center the worm wheel 35 has a squared socket 45.

Attached to the under side of the chassis frame member 15 is a journalbox 37, within which is mounted the shaft 36 with its squared end 40fitting in the squared socket 45 of the worm wheel 35. The shaft 36carries a collar 38 and set screw for the same by which it may be keptin place. At its end the shaft '36 carries a cable-winding drum 39. Atthe front and rear ends, the chassis frame member 15 carries rings oreyes 41- and 42, through which a cable 43 may be passed. This cable 43is given one or more turns about the drum 39 and the free end is passedback as designated at 43'.

Normally the gears 22 and 18 are out of mesh, as shown in Fig. 4, sothat the automobile operates without operating the drum 39. Also, whenthe automobile is in ordinary use, the shaft 36 may be removedbyloosening the collar 38, and the shaft 36 and drum 39 may be carriedwithin the body of the automobile. When it is desired to use them forthe purpose intended, the shaft 36 and drum 39 .can be quickly appliedas shown in Fig. 2, the squaredend 40 of the shaft 36 being thrust intothe squared While the automobile engine is running, the v operator,standing on the ground with the end 43 in his hands, can tighten thecable 43 on the drum 39 so that the drum will engage the cable and windit thereon. Thus the automobile can be slowly pulled out. If, instead,it is desired to back the automobile out, this can be done by passingthe cable through the ring 42 instead of 41.

It will be seen that the stress on the automobile frame, due to the pullon the cable 43, is transmitted directly to the side-bar 15, so thatthere is no danger of wrenching or destroying any part of the machine.

As already explained, thedrum 39 can be quickly removed or replaced. Itwill be seen that the apparatus is not inthe way, and that it isentirely disconnected mechanically from the transmission mechanism whenthe automobile is in ordinary use.

I claim:

1. In combination with an automobile having transmission gearing and acasing therefor, a worm wheel j ournaled beside the casing, said wormwheel having a non-cir cularcentral hole therethrough, a shaft with acorrespondingly shaped end removably engaging said hole, a journal forsaid shaft on the frame of the automobile, a winding drum on the end ofsaid shaft remote from the worm wheel, a worm engaging said worm wheel,a shaft carrying said'worm, a gear wheel mounted on said shaft with aslot and key connection, and means to shift said gear wheel in and outof connection with another gear wheel of said transmission gearing.

2. In combination with an automobile having transmission gearing and acasing therefor, a wheel .journaled on the side of the casing,said wheelhaving 'a non circ'uIar hole through the'center,,a journal carried bythe automobile frame in alinementwith said hole, a shaft in said journalwith a noncircular end engaging said hole, a winding drum carried by theprojecting end of said shaft, gearing from a gear wheel of thetransmission gearing to said first mentioned .Wheel, and manuallyoperated means to consupplemental casing adapted to transmit rotationfrom a gear of the main transmission gearing to said shaft. 1 I.

4. In combination with an automobile, a winding drum, a gear wheelmounted adjacent to the transmission gear casing of the automobile, saidgear wheel having a squared socket, a shaft carrying said winding drumand having a squared end to engage said socket, and means to drive saidgear Wheel from the transmission gearing of the automobile.

5. In combination with an automobile having a gear casing and alongitudinal side frame member, a journal bearing on said member, asupplemental gear casing on the side of the transmission gear casing, agear wheel within said supplemental gear casing, said gear wheel havinga squared socket, a winding drum, a shaft carrying the said winding drumand journaled in said journal bearing, said shaft having a squared endentering the squared socket of the said gear wheel, and mechanism todrive said gear wheel from the transmission gear of the automobile.

In testimony whereof, I have" subscribed my name. ADOLPH MONSEN.
